Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?
At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.
This paper presents a rigorous construction and uniqueness proof for the matrix Green's function of coupled radial Schrödinger equations with symmetric potentials, demonstrating its diagonal Wronskian structure and illustrating its application in capturing multistep excitation pathways within the continuum-discretized coupled-channels framework.
This paper investigates the photoproduction and nuclear absorption of charmonium on C and W targets near the kinematic threshold using a collision model with nuclear spectral functions, demonstrating that calculated observables are sensitive to absorption scenarios and could help determine the -nucleus cross section for future experiments at the CEBAF facility.
This paper establishes an analytical connection between triaxial nuclear shapes and three-particle correlations in relativistic heavy-ion collisions, demonstrating that specific flow and momentum fluctuation observables are directly proportional to the nuclear triaxiality parameter .
This paper demonstrates that Bose polarons immersed in a Bose-Einstein condensate can exhibit topological properties, including emergent Weyl nodes, nonzero Berry curvature, and chiral anomaly, driven solely by interspecies -wave Feshbach coupling without the need for spin degrees of freedom or spin-orbit coupling.
Using the Bethe-Salpeter formalism within the impulse approximation, this paper computes the isospin-breaking baryonic form factors for pions and kaons, yielding a baryonic radius of 0.043(2) fm for the pion that aligns with dispersive benchmarks and predicting larger radii of approximately 0.26 fm for kaons that are compatible with chiral QCD models.
This paper presents calculations of space-like electromagnetic form factors and charge radii for both light and heavy-light pseudoscalar mesons using a flavor-dependent Bethe-Salpeter framework.
This paper presents a novel, numerically and formally exact solution to the pion Bethe-Salpeter equation in the chiral limit, utilizing state-of-the-art QCD correlation functions while strictly satisfying axial Ward-Takahashi identities.
This paper presents a unified microscopic framework based on a symmetry-restored multi-excitation generator coordinate method to derive non-local optical potentials from an effective Hamiltonian, successfully applying it to calculate neutron scattering cross sections for deformed chromium isotopes while consistently treating nuclear structure and reaction observables.
This paper predicts that the spin Hall effect in hot and dense QCD matter, induced by baryon chemical potential gradients in heavy-ion collisions, can be detected through the distinct sign and beam energy dependence of the second Fourier coefficients of net hyperon spin polarization using a (3+1)D viscous hydrodynamic model.
Using time-domain terahertz emission spectroscopy, researchers observed a dynamic magneto-chiral instability in photoexcited tellurium, where an electric current parallel to a magnetic field amplifies electromagnetic waves, offering a promising mechanism for THz-wave amplification in chiral materials.
